Yes - you should be able to.
The propertiy is called %UpdatedBy% in PFrank.

First go to the Options window and select the %UpdatedBy% keyword for insertion.
Then on the main window you have to select one of the "Insert Office Properties" pre-defined commands and insert it in the custom renaming list.

Everything I've read indicates that there is a restriction of 260 chars for total path length and 256 characters for max file length in Windows. PFrank wil raise errors if the total path is > 256 - I might have to adjust this to to 260.

The reason that I allowed the max path filter to be confgured up to 512 characters is because a user requested it. I think the reason it was required was that they were using a filesystem that allowed more than 256 characters for the total path and they wanted to be able to log those filenames with their lengths using PFrank (this is possible on the detailed window).
Paths greater than 256 are possible on some linux systems; We have such a system where I work. I created files with total path that was much more than 256 using linux but when I go to access those files using windows XP I can't do anything with them because WIndows is incapable of opening them.
I think the same thing would happen with Windows 2003.

Are you able to manually create pathnames with lengths > 256 on your system?

A fail message will show up as long as there is at least 1 file to rename.
The "Renaming Successful" message that you are seeing is a bug. It occurs if the scan results in all files having errors. i.e. there are 0 files to rename.
I'll fix that.

As for aborting if there are any scan errors, that is a good suggestion. I'll make that a command line option in the next release.

I've made a beta that will print warnings in the log file if any problems occur in a command line initiated renaming.
There are also 2 new options - '-e' to abort if there are any scan errors, and '-w' to abort if there are any warning errors.
